WHEEL TREAD.

Specification of Letters Patent. Patentgd Jan, 10 .1922

Application filed October 3, 1919. Serial No. 328,144.

is to provide a wheel tread which may be removed from a wheel body readily without taking apart the constituent membersot the wheel tread. A further object. of to provide novel means whereby the tire proper may be adjusted to vary the resiliency thereof.

\Vithin the scope f what is claimed, a mechanic may work changes in the structure shown, without departing from the spirit of the invention.

In the drawin :Figure 1 shows in side elevation, a wheel wagon whereon the tread hereinafter described has been mounted; F igure 2 is a cross section through the wheel body and parts associated therewith; Fig-.

ure 3 is a cross section showing the parts as they will appear during the removal of a portion of the wheel tread; Figure 4 is a fragmental side elevation wherein parts are broken away; Figure 5 is a tragmental cross section showing a modification.

The numeral 1 marks a wheel body including a fell-y 2 carrying a felly band 3 forming part of; the wheel tread hereinafter claimed. At 4% there appears a side plate having a trough-shaped offset 5 receiving one edge of the telly band 3. The numeral 6. designates a side plate havin no element corresponding to the part 5 am of sufiicient diameter so that it can move externally of the band 3 toward and away from the plate 4:. Theside plates 6 and 4c are provided with outwardly flaring flanges 7 which may be curved to conform to the cross section of a tire 8 which may be made of solid rubber or other suitable material. The tire 8 is supplied with a circumferential groove 9 in its inner edge. The numeral 10 denotes an, expander in the form of a ring having beveled edges 11 cooperating with the inner surfaces of the flanges 7, the expander engaging the tire 8. The expander 10 may be severed at one or more places, as shown at 12 in Figure 4, to the end that the diameter of the expander may be increased or diminished in the operation of the device. A. retaining ring lat is provided, the same. having a trough-shaped offsetv 15 receiving one edge of the telly band or base plate 3. The ring is provided with openings 18. Securing devices, such as bolts" 16, connect the side plate l with the ring 14 and hold the flsets 5 and 15 in engagement with the edges of the telly band 3. The side plate 6 is mounted on the securing devices 16 for sliding movement toward and away from the side plate 4. Tightening devices 17, which may be bolts, connect the side plate t with the side plate 6, the heads of these bolts being received in the open ings 13 'ot the ring 14.

hen the bolts 16 are removed, the tire 8, the side plates i and 6 and the expander 10 may be slid laterally off the wheel body 1 without taking down the structure comprising the parts above enumerated. See Fig. 3.

The bolts 17 may be tightened up, thus drawing the side plate 6 inwardly. When the side plate 6 is drawn inwardly the beveled edges 11 01"? the expander 10 cooperate with the flanges 7 of the side plates 6 and at, the diameter of the expander being increased, and the tire 8 being expanded and hardened accordingly. The operator, therefore, has within his command, a simple means whereby the resiliency of the tire 8 may be adjusted.- I

. The flanges of the side plates need not be of the particular form shown in Figure 2. Thus, the flanges. may be straight as shown in Figure 5: in that figure, parts hereinbefore described are designated by numerals previously used, with the suflix a.
